During a conference call with reporters earlier today, a Romney surrogate was asked if the candidate would repeal the law, which was the first bill signed by President Obama and expanded the rights of workers to pursue legal action on pay discrepancies between men and women. The response: "We'll get back to you on that."

Since the topic of the call was what the Romney campaign calls the Obama administration's "war on women," Democrats jumped on the lack of an answer.

Obama's campaign circulated a statement from Ledbetter, who was the plaintiff in a discrimination suit: "I was shocked and disappointed to hear that Mitt Romney is not willing to stand up for women and their families. If he is truly concerned about women in this economy, he wouldn’t have to take time to ‘think’ about whether he supports the Lilly Ledbetter Fair Pay Act."

Michigan Democrats were similarly critical. State Senate Minority Leader Gretchen Whitmer issued a statement: "What does Mitt Romney need to think about when it comes to supporting fair pay and equal treatment for women in the workforce? As a mother of two daughters, I find it outrageous and dispiriting that the presumptive Republican nominee for President can’t – or won’t – take a clear position on the Lilly Ledbetter Act that ensures equal pay for equal work."

"Women account for more than 92% of jobs lost under Barack Obama. Of course Mitt Romney supports pay equity for women," a campaign spokeswoman said. "The real question is whether President Obama supports jobs for women."
